Hi David How did you (or the AA) manage to get to the battery? With no, or low, battery the boot can't be opened as there is no mechanical system (as there is for the doors). I have had the same problem and the AA man had to wiggle his way via the back seats.

I have the same problem with my 2023 450h+. I won't repeat what everyone is saying other than to add that I travelled home from North Wales last Saturday, running entirely on petrol, did about 50 miles on Sunday and similar on Monday, then this morning - battery flat. So it is not primarily when a car has not been much used that the 12v battery dies. This has happened to me twice in the 9 months I have had the car. It completely disables the car which can be a disaster. The boot cannot be opened manually so it can be very difficult to access the battery - you have yo go in through the back seat, if you can open that door. It seems to me like a 'Don't buy this car' issue.
